DESCRIPTION OF THE EMBODIMENTS

The following is the present Invention by illustrative examples with reference to the accompanying Described drawings.

First, a structure of the optical Plate are described.

(1) Physical structure an optical disc

1A Fig. 12 is an external view of an optical disk 100 in an example according to the present invention. The optical disc 100 is z. B. a DVD, which is a multi-media optical disc. 1B Fig. 14 is a view showing a cross section of the optical disk 100 shows which along the line XX 'in 1A runs. 1C is an enlarged view of section Y shown in 1B is shown.

As in 1B is shown, the optical disc by laminating a first transparent substrate layer 108 , an information layer 109 , an adhesive layer 110 , a second transparent layer 111 and a print layer 112 trained to print a label in this order.

The first transparent substrate 108 and the second transparent substrate 111 are reinforcement substrates which are made of an identical material. In the example, which in 1B is shown have the first transparent substrate 108 and the second transparent substrate 111 each about 0.6 mm thick. The first transparent substrate 108 and the second transparent substrate 111 have a thickness in the range of about 0.5 minutes to about 0.7 mm.

The adhesive layer 110 is between the information layer 109 and the second transparent substrate 111 arranged to the information layer 109 and the second transparent substrate 111 connect with each other.

From the two main surfaces of the information layer 109 is the main surface, which is with the first transparent substrate 108 is in contact with a reflective film (not shown) disposed thereon. The reflective film is made of a thin metal film or the like. The reflective film has concave and convex dimples, which are formed in a high density by a molding technology.

1B shows a shape of the dimples formed in the reflective film. In the example, which in 1C each dimple is from about 0.4 µm to about 2.13 µm in length. The optical disc 100 has a spiral track on it. Each dimple is formed along the spiral track such that two adjacent dimples are in the radial direction of the optical disk 100 are arranged approximately 0.74 μm apart. Thus, a plurality of dimples are formed in the spiral track.

If the optical disc 100 through an optical beam 113 is irradiated becomes an optical point 114 on the information layer 109 trained in how this 1C is shown. Information on the optical disc 100 are stored as a change in the reflectance of a portion of the information layer 109 that with the optical point 114 is irradiated, recorded.

The diameter of the optical point 114 on the optical disc 100 is approximately 1 / 1.6 of the diameter of the optical point on a CD (compact disk). The reason for this is that the numerical aperture (NA) of an objective lens for the optical disk 100 is larger than the numerical opening NA of an objective lens for the CD, and the wavelength λ of the optical beam for the optical disk 100 is shorter than the wavelength λ for the CD.

The optical disc 100 , which has such a physical structure, may have stored approximately 4.7 gigabytes of information on one of its pages. The capacity of approximately 4.7 gigabytes is close to eight times the capacity of a conventional CD. Such a large optical disk capacity 100 can significantly improve the quality of moving pictures and also significantly increase the playback time period of moving pictures. While the playback time period from the conventional video CD is 74 minutes, the playback time period of the DVD is 2 hours or more.

The fundamental technology that realized such a large capacity is the reduction of the spot diameter D of the optical beam. The point diameter D is given by the statement: point diameter D = wavelength λ of the laser beam / numerical opening NA of the objective lens. Accordingly, the spot diameter can be lengthened by shortening the wavelength λ of the laser beam and increasing the numerical opening NA of the objective lens. It should be noted that if the public number NA NA of the objective lens is raised because of the relative inclination (ie the skew) of the surface of the optical disc 100 image aberrations arise in relation to the axis of the optical beam. For the optical disc 100 is the image aberration by reducing the thickness of the first and / or second transparent substrates 108 and 111 reducible. If the thickness of the first and / or second transparent substrates 108 and 111 another problem may exist, namely that the mechanical strength of the optical disk 100 is reduced. The strength of the optical disc 100 is by providing another substrate on the first and / or second transparent substrate 108 and 111 reinforced, thus solving the problem of mechanical strength.

To the on the optical disc 100 To read the recorded information, red semiconductor laser light with a wavelength as short as 650 nm and an objective lens with a numerical aperture (NA) as large as approximately 0.6 mm will be used. By further using a transparent substrate, about 0.6 mm thin as each of the first and second transparent substrates 108 and 111 can hold information of approximately 4.7 gigabytes on one side of the optical disk 100 saved with a diameter of 120 mm.

2A schematically shows a spiral track 20 from an inner area to an outer peripheral area which is in the information layer 109 the optical disc 100 is trained. The spiral track 20 is divided into mandatory units, which are referred to as sectors. In 2 are the sectors through S1 . S2 , ... S99 and S100 shown. Information on the optical disc 100 are read out on a sector-sector basis.

2 B shows an internal structure of the sector. The sector contains an area of the sector header 21 , a user data area 22 and a storage area 23 for an error correction code.

The area of the sector header 21 has a sector address to identify the sector and an error detection code for the sector address stored therein. Based on the sector address, a disk player determines which sector to read from the plurality of sector information.

The user data area 22 may have 2 KB of information stored therein.

In the storage area 23 for an error correction code are an error correction code for the area of the sector file header 21 and the user data area 22 which is in the sector that contains the memory area for the error correction code 23 contains, is contained, saved. For reading the data from the user data area 22 the disk player performs error detection using the error correction code and performs error correction according to the results of the error detection. This ensures reading security.

In the program information table 1012 The audio title set is a variety of groups of program information 1026 (ATS_PGI) of the audio title set. The program information (ATS_PGI) 1026 of the audio title set represents information on programs contained in an audio title.

In each of the multitude of groups of program information 1026 The audio title set contains the following information: Information about the physical arrangement of the audio program 1041 (which indicates whether an AOB corresponds to the present audio program and an AOB corresponds to the immediately preceding audio program at physically successive positions on the optical disk 100 is included or not), feature information 1042 regarding the audio program time (which indicates whether the time information on the AOB corresponds to the present audio program and the time information on the AOB corresponds to the audio program immediately preceding it, is consecutive or not), a start cell number 1043 of the audio program (which indicates the first cell number contained in the audio program), an audio cell time 1044 of the playback start (which indicates the start time of the first audio cell included in the audio program), a time period 1045 the total playback of the audio program (which indicates the total playback time period of the audio program), one time period 1046 the audio pause (which indicates the quiet period of time before playback of the first audio cell included in the audio program starts) and the like.

In the playback information table 1013 the audio title set cell is a variety of groups of playback information 1027 the audio bibliographic record cell (ATS-C_PGI) 1027 described. Each group of audio bibliographic cell playback information 1027 represents information about the cell which corresponds to the AOB to be reproduced.

In each group, the plurality of groups of playback information 1027 The audio bibliographic cell has the following information: a cell index number 1051 , which indicates the order of the cells contained in the audio program, a cell type 1052 , which indicates the type of cell, a cell start address 1053 , which indicates the start address of the cell, a cell end address 1054 which indicates the end address of the cell, and the like.

The cell type 1052 shows z. B. whether the cell is a quiet cell or an audio cell. The cell start address 1053 and the cell end address 1054 are, for example, using a relative address with respect to the first pack of the first AOB that is in the audio title set 900 is described.

The rendering information table 1014 of the audio title set audio still video contains a plurality of search pointers of the playback information of the audio title set audio still video (ATS_PG_ASV_PBI_SRP) 1028 and a plurality of groups of audio title set audio still video playback information (ATS_ASV_PBI) 1029 ,

Any search pointer 1028 the playback information of the audio title set-audio still video corresponds to each program contained in an audio title set. Accordingly, the number of search pointers 1028 the playback information of the audio title set audio still video is equal to the number of groups of the program information 1026 of the audio bibliographic record.

In every search pointer 1028 The playback information of the audio title set-audio still video describes the following information: a number 1061 the audio still video unit (ASVUN) (which is the audio still video unit 513 indicates which is used for program playback), an audio still video playback mode (ASV_DMOD) 1062 and a start address 1063 and an end address 1064 the playback information 1029 of the audio still video (ATS_ASV_PBI) used for program playback.

As the number 1061 the audio still video unit 513 becomes the number that conforms to the playback order of the audio still video unit 513 in the audio still video set 500 is described.

The audio still video playback mode 1062 includes a display timing mode and a display order mode. As the display timing mode, the "slide show mode" or the "scroll mode" can be named; and as the display order mode, the "sequence mode, the" random mode "or the" mixing mode "can be named.

Each group of audio title set audio still video playback information 1029 contains a variety of audio still video display lists (ASV) 1071 , As the data structure of the display list of the audio still videos 1071 are four different data structures, which are related to the playback mode 1062 of the audio still video can be used. Two data structures are defined for the display timing mode, one for the "slide show mode" and one for the "flip mode". Two data structures are defined for the "display order mode", one for the "sequence mode" and one for the "random mode" or the "mixed mode". Four (2 × 2) data structures are thus defined. In the following the four data structures will be described one after the other.

The 11A shows a data structure of the display list 1071 the audio still video when the display timing mode is the "slide show mode" and the display order mode is the "sequence mode".

In the display list 1071 of the audio still video, the following information is described: an ASV number (ASV number) 1101 , a specified video stream existence flag (input DLIST flag) 1102 , a button number 1103 which was forcibly selected (FOSL_BTNN: forcibly selected button number), a program number (program number) 1104 , information regarding the display timing 1105 (Display clocking), a start effect mode (start effect mode) 1106 , an effect mode (effect mode) 1107 , a start effect period (start effect period) 1108 and an end effect period (end effect period) 1109 ,

The ASV number 1101 is information about the naming of the audio still video object 521 which consists of at least one audio still video object 521 which is in the audio still video unit 513 is shown.

The specified existence flag of the video data stream 1102 has the value "1" or "0". The value "1" of the specified existence flag 1102 of the video data stream indicates that the audio still video, which is in accordance with the playback information 1029 of the audio still video that has the specified existence flag 1102 of the video data stream contains the specified video data stream to be used for the menu. The value "0" of the specified existence flag 1102 of the video data stream indicates that the audio still video, which is in accordance with the playback information 1029 of the audio still video is reproduced, which has the specified existence flag 1102 of the video stream includes a different video stream than the specified video stream to be used for the menu.

Only two operating states are permitted within a program (PG). In an operating state, one of the plurality of those specified has an existence flag 1102 the video data stream has the value "1" and the other flags have the value "0"; in the other operating state has the entire multitude of specified existence flags 1102 of the video data stream the value "0". The existence of a specified existence flag 1102 of a video data stream with the value "1" in the program (PG) indicates that a specified video data stream to be used for the menu exists in the program. The non-existence of a specified existence flag 1102 of the video data stream with the value "1" in the program (PG) (ie all specified existence flags 1102 the video data streams in the program (PG) have the value "0") indicates that no specified video data stream is to be used for the menu in the program.

The forcibly selected button number 1103 shows the selected button number as a suggestion if the named still picture by the ASV number 1101 is shown.

The program number 1104 and the display "No information" 1105 are information on the naming of the timing of the start of the display of still pictures, which is indicated by the ASV number 1101 were named. In other words, once the program is playing, which is identified by the program number 1104 was designated a playback time by the playback timing information 1105 have been reached, the display of the still image and the button is in accordance with the display list 1071 displayed.

The start effect mode 1106 and the bottom line mode 1107 are information about the naming of applied display effects when switching from one still picture to another still picture. For example, display effects such as "fade", "cut", "volatilize" and "wipe" through the start effect mode 1106 and the bottom line mode 1107 named.

The start effect period 1108 and the bottom line period 1109 is information which is the period of time in which the display effect set by the start effect mode and the end effect mode is maintained.

11B shows a data structure of the display list 1071 of the audio still video if the ad Clocking mode is the "slide show mode" and the display order mode is the "random mode" or the "mixed mode".

The data structure, which in 11B is identical to the data structure shown in 11A is shown, except that the ASV number 1101 in 11A through a reserved area (reserved) in 11B is replaced.

In the display list 1071 in 11B must have the ASV number 1101 not necessarily be named. The reason for this is that although the timing to switch a still picture to another still picture is by the program number 1104 and the display timing information 1105 (Adaptation) is named, the next still picture to be displayed is determined randomly.

In "random mode" the audio still video object, which one next must be displayed, completely random from the audio still video unit certainly. In the "mix mode" the audio still video object fortuitously determined, but the audio still video object that was selected once, will not be selected again until all the other audio still video objects have been selected are.

The contents of the reserved area are not specified. The reserved area is e.g. B. empty.

11C shows a data structure of the display list 1071 the audio still video when the display timing mode is the "flip mode" and the display order mode is the "follow mode".

The data structure, which in 11C is identical to the data structure shown in 11A is shown, except that the program number 1104 in 11A through a reserved area in 11C (reserved) is replaced, and that the display timing information 1105 in 11A through a maximum display period (maximum period) 1111 and a minimum display period (minimum period) 1112 in 11C is replaced.

In the display list 1071 in 11C is neither the program number 1104 still the display timing information 1105 must be named. The reason for this is that the "leaf through mode" is switched from one still picture to another still picture in response to the input of a user at any time. This allows the viewer to freely switch sides.

The maximum display duration period 1111 is used for the automatic scrolling forward, even if there is no input from the user. If there is no input from the user even after the maximum display duration period 1111 the still image is automatically switched to the next still image.

The minimum display time 1112 is used to display the still image, which is identified by the ASV number 1101 is intended to be used for a minimum period of time. Until the time period, which is determined by the minimum display period 112 is determined, passes, the still image is not switched to the next still image, even if the user has made an entry.

11D shows a data structure of the display list 1071 the audio still video, in the event that the display timing mode is the "flip mode" and the display order is the "random mode" or the "mix mode".

(4.2.3) Administrative information 911 the audio bibliographic record (if the audio bibliographic record 900 an audio object 923 not included)

With renewed reference to the 9B refers to the audio bibliographic record 900 the video objects for the video title set contained in another video title set. As a result, a video object for a video title set title is reproduced instead of the audio object. In this case, the basic structure that the administrative information 911 of the audio bibliographic record the management table 921 of the audio bibliographic record and the PGC management information table 922 contains, maintain.

The administration table 921 of the audio bibliographic record and the PGC management information table 922 are different in this case from the case where the audio title set 900 the audio object 923 contains.

In the administration table 921 of the audio bibliographic record will be used instead of the location 931 of the audio object, the address information on the video title set including the related video object and the storage position of the video object in the video title set are described.

The administrative information table 922 of the PGC does not include the playback information table of the audio title set audio still video. The reason for this is that it is not necessary to refer to the audio still video since the video object already contains video information.

(4.3) Audio manager 1200

12 shows a data structure of the audio manager 1200 , The audio manager 1200 is information for the reproduction control to which the disc player first refers to reproducing the optical disc with a priority directed to audio information.

The audio manager 1200 contains audio manager information (AMGI) 1211 , an audio manager menu VOB (AMDM_VOBS) 1212 and a backup copy of the audio manager information (AMGI_BUP) 1213 ,

The audio manager information 1211 contains a management table for the audio manager information (AMGI_MAT) 1221 , which contains feature information and pointer information, admin maintenance information 1222 of the audio title including the number of audio titles and the like, a plurality of audio title search pointers (ATT_SRP) 1223 , each containing search information of the audio title, and an information table relating to PGC management of the audio manager menu (AMGM_PGCI_UT) 1224 which contains the PGC information for an audio manager menu.

The administration table 1221 the audio manager information includes an AMG identifier (AMG_ID) for identifying the audio manager 1200 , an AMG end address (AMG_EA), which is an end address for the table management, an AMGI end address (AMGI_EA), a version number (VERN), an identifier for a data carrier set (VLMS_ID), a bibliographic record number (TS_NS), which the number of Indicates bibliographic records contained on the data carrier, an identifier of the supplier (PVR_ID) to identify the supplier who designed the disc, an AMGI MAT end address (AMGI_MAT_EA), an automatic execution flag (Auto_Play_Flag) to define the mode of operation of the playback device , when the disk is input, and an ASVS start address (ASVS_SA) record of the position of the set of audio still pictures, address information in tables for AMG and AMGI and AMGM_VOBS feature information, which VOB feature information is contained in the audio manager , contain.

Although not in 12 shown contains each search pointer table 1223 of the audio title, an "audio title type" indicating the type of each title, an "in-title program number" indicating the number of programs contained in the title, a period of "title playback", indicating the playback time period of the title, a number of the "audio title set" indicating the number of the audio title set to which each title belongs, a number of the "ATS title" indicating the title number of each. Displays the title in the audio title set and an "ATS address" which indicates the address of the audio title set to which each title belongs.

13 shows schematically the correspondence between the ASV and ATS on the optical disc 100 are saved.

The ATS can contain a variety of groups of PGC information (ATS_PGCI). However, in the example included in the 13 ATS is a group of PGC information (ATS_PGCI). The PGC information describes the playback order of audio programs in an audio program group (program # 1, program # 2, ... program #L). Every audio program is an access unit to audio data. Each audio program contains a large number of pieces of playback information of the audio cell (ATS_C_PBI). The playback information of the audio cell is a minimal management unit. The playback data of an audio cell point to an AOB which contains current audio data. The audio data which have to be reproduced corresponding to the audio program are thus determined.

The PGC information describes playback information of the audio still video (ATS_ASV_PBI), which specifies how the still image is to be reproduced on a program-program basis. A variety of audio programs can share the same playback information of the audio still video. In the example shown in 13 program # 1 and program # 2 ATS_ASV_PBI # 1 are shown. The reason for this is that the playback information table of the audio still video (ATS_ASV_PBIT) is structured in such a way that ATS_PG_ASV_PBI_SRP, which corresponds to the audio program, points to one of the plurality of groups of ATS_ASV_PBI.

The PGC information names one ASVU, which is included in the ASV to provide a variety of still images in relation to to play the audio program. play.

The ASVU is also a unit used by the playback device to buffer still image data. In particular, the playback device reads a data group of still images in the named ASVU from the optical disk before the playback of an audio program 100 out. Accordingly, the playback device does not need the set of still picture data from the optical disc 100 Read while playing the audio program (e.g. the music program).

Before the next audio program is played back, the playback device determines whether the data group of the still picture in the ASVU, which is requested for the next audio program, exists in a main memory of the playback device. If the data group of the still picture required for the next audio program exists in the ASVU in the main memory of the playback device, the playback device does not have to again the data group of the still picture from the optical disk 100 Read.

If the producer of the audio track wishes that from one audio program to the next Audio program is switched quickly, the PGC information be structured such that an audio program and a next audio program share an ASVU. By structuring the PGC information in this way, the playback device does not need the data group of the Still pictures in the ASVU, which are required for the next audio program, buffer. As a result, the playback device can quickly switch between two audio programs, which are continuously played back and forth.

The ATS_ASV_PBI manages the order of the still images, which are to be displayed in the form of a disc display list (ASV_DLIST). In In the display list (ASV_DLIST), the still picture in the ASVU that is to be reproduced is named by the ASV number.

As described above, it allows the PGC information, different still images for different Play audio programs. The PGC information also allows the same still picture for play a variety of audio programs. If an audio program the still images to be played back can be switched to another audio program be switched without the need to mute.

14 shows schematically the correspondence between the audio programs, AOBs, cells, ASVUs and ASVOBs that are on the optical disc 100 are saved. Such correspondence is defined by the PGC information (ATS_PGCI). In 14 the arrow t represents the time axis. In the example shown in 14 an audio track contains four audio programs. The audio program No. 1 corresponds to AOB # 1, the audio program # 2 corresponds to AOB # 2 and the audio programs # 3 and # 4 correspond to AOB # 3. Here are the AOBs on the optical disk 100 in the order AOB # 1, AOB # 2 and then AOB # 3. Audio program # 1 contains cells # 1 and # 2; The audio program # 2 contains cells # 3, # 4 and # 5; audio program # 3 contains cells # 6 and # 7; and audio program # 4 contains cells # 8. Cells # 1, # 3 and # 6 are quiet cells and cells # 2, # 4, # 5, # 7 and # 8 are audio cells.

The audio programs # 1 and # 2 correspond with the ASVU # 1, and the audio programs # 3 and # 4 correspond to ASVU # 2. The display of ASVOB # 1 is started in synchronization with the playback start of the cell # 2; the playback of ASOB # 2 is in synchronization with the playback start cell # 4 started. The display of ASVOB # 3 is in synchronization started with playback of cell # 5; and the display of ASVOB # 4 will be in synchronization with the playback start of the cell # 7 started; and the display of ASVOB # 5 will be in synchronization started with playback of cell # 8.

15 shows an example of the content of the program information 1026 and content of the search pointer 1028 the playback information of the audio still video relating to each of the audio programs # 1 to # 4. In the example shown in 15 is shown, it is assumed that the playback period of each audio cell 60 Seconds (5,400,000 in PTS (presentation time stamp)) and that the playback time period of each rest cell is one second (90,000 in PTS). 16A shows exemplary content of the playback information 1029 of the audio still video (ATS_ASV_PBI # 1) corresponding to the audio programs # 1 and # 2, which in 14 are shown.

The 16B shows exemplary content of the playback information 1029 of the audio still video (ATS_ASV_PBI # 2) corresponding to the audio programs # 3 and # 4, which in 14 are shown.

17 shows exemplary content of the playback information 1027 the cell pertaining to each of cells # 1 to # 8 that are in 14 are shown. In the example, which in 17 is shown, it is assumed that the audio data are encoded with a sampling rate of 48 kHz and 16 bits and 2 channels. In this case, the number of packs of the quiet cells 96 and the number of packs of audio cells is 5,760.

18 shows an example of content from ATS_PG_ASV_PBI # 1 to # 5. In the example, which in 18 is shown, it is assumed that the number of still picture packs 50 is. 19 shows exemplary content of general information of the audio still video unit (ASVU_GI). The addresses 1053 and 1064 ( 15 ) the playback information of the audio still video, which is in the search pointer of the playback information of the audio still video 1028 is included can be represented by e.g. B. a relative address, which uses the position at which the first ASVOB is included as a reference address. However, as long as the position of the ASVOB on the optical disk can be specified, the addresses can 1063 and 1064 can be represented by any address. For example, the addresses 1063 and 1064 , when the general information of the audio still video unit (ASVU_GI) contains address information which is suitable as a reference address, is represented by relative addresses with respect to this reference address.

In the example, which in 15 is shown is the ASV playback mode 1062 of audio programs # 1 and # 2 "slide show mode". In this case, the still picture is reproduced in synchronization with the audio information. As the ASVU no. 1061 of the audio programs # 1 and # 2 is "1", the ASVU # 1 is stored in the buffer of the playback device before the playback of the audio programs # 1 and # 2. Next, refer to ATS_ASV_PBI # 1 based on the addresses 1063 and 1064 the ATS_ASV_PBI. As a result, the display of the still pictures corresponds to the display lists # 1, # 2 and # 3 of the ATS_ASV_PBI # 1 that are shown in 16A is shown at a display timing by the program number 1103 and the display timing information 1105 is started. The display timing is in synchronization with the playback time of the audio information that is to be played back together with the still images.

In other words, the display of still pictures designated by the display list No. 1 of ATS_ASV_PBI # 1 is started when PTS becomes 90,000 during the playback of AOB # 1. The display of the still pictures, which by display list # 2 of ATS_ASV_PBI # 1 is named when PTS becomes 90,000 during the playback of AOB # 2. The display of the still pictures, which is designated by the display list # 3 of the ATS_ASV_PBI # 1, starts when PTS becomes 5,580,000 during the playback of AOB # 2. When the ASV playback mode 1062 is set to "slide show", the display of the still picture is shown with a timing which is synchronized in synchronization with the audio playback time, as described above. The still image cannot be renewed by the instruction of a user.

20A schematically shows the relationship between the playback timing of the audio program and the display timing of the still picture when the ASV playback mode 1062 "Slide Show" is.

In the example shown in 15 is shown is the ASV playback mode 1062 of audio programs # 3 and # 4 the "flip mode". In this case, the still picture is reproduced asynchronously with the audio information. The display of the still images corresponding to the advertisement lists # 1 and # 2 of the ATS_ASV_PBI # 2, which in 16B is shown is renewed in response to an operation or a command from the user. If no operation by the user within the time period of the playback time, which is indicated by the period information 1111 the maximum display time is specified, the still picture is automatically switched to the next still picture.

To play the audio program # 3, the ASVU # 2 is based on the ASVU no. 1061 selected corresponding to audio program # 3. Before the playback of the audio program # 3, the ASVU # 2 is read into the buffer of the playback device. Next will focus on the ATS_ASV_PBI # 2 based on the addresses 1063 and 1064 the ATS_ASV_PBI related. Because the audio program number 1104 the display list # 1 of the ATS_ASV_PBI # 2 is "3", the ASVOB # 4 is based on the ASV no. 1101 display list # 1 is displayed.

When a button of the remote control or the like corresponding to Next_DLIST is pressed, which orders the display of the next display list, the ASVOB # 5 is based on the ASV No. 1101 display list # 2 of ATS_ASV_PBI # 2 is displayed. When the display is switched from ASVOB # 4 to ASVOB # 5, the display effects become in accordance with the start effect mode 1106 , the bottom line mode 1107 and the start effect time period 1108 and the bottom line period 1109 made available.

If the user does not operate during the time period of the playback time of 5,490,000 (ie, about 1 minute), which (time period) by the period information of the maximum display time 1111 the display list # 1, the ASVOB # 5 is based on the ASV no. 1101 of the next display list # 2 is displayed. The time period of the display time of 5,490,000 matches the time period for the playback of the audio program # 3.

After playing the audio program # 3 completely carried out audio program # 4 is played. Provided during the Play the audio program # 3 If the user is operated, the display of ASVOB # 4 toggled to display ASVOB # 5 during the Play the audio program # 3. Unless during no playback of the user takes place when playing the audio program # 3, ASVOB # 5 will display simultaneously with the start of playback of the audio program # 4 started.

When playback from audio program # 4 has started; ASVU # 2 is based on ASVU no. 1061 corresponding to the audio program # 4 is selected, and ASVU # 2 is inserted into the buffer of the playback device before the audio program # 4 is played. After that, it will be based on the addresses 1063 and 1064 the ATS_ASV_PBI related to the ATS_ASV_PBI # 2. Because the first display list from the set of display lists contained in ATS_ASV_PBI # 2, which "4" as the audio program number 1104 display list is # 2; becomes ASVOB # 5 based on ASV no. 1101 the display list # 2.

After ASVOB # 5 was presented, the display of ASVOB # 5 will respond to the response from the operator of the User or command of the user. The audio program number of the Display list is only effective if the ASVU is changed. In this case, will. on the audio program number of the display list related to determine the first ASVOB to be played.

20B schematically shows the relationship between the playback timing of the audio program and the display timing of the still pictures when the ASV playback mode 1062 " Browse mode "is.

If the value of the period information 1111 Regarding the maximum display time, a value that represents the "infinity", the corresponding ASVOB is continuously displayed until the operation of the user is carried out or a command is executed. Since the value represents infinity, the maximum value (ie the binary value in which all digits are "1") can be used, but all other values can also be used. In the case of the "flip mode", a value representing "infinity" can always be in the period information 1111 regarding the maximum display time.

As described above, AOB and ASVOB are reproduced simultaneously by one decoder ben, in contrast to the reproduction of the VOB.

The VOB and the reproduction process of the AOB and ASVOB are in each other identical that the video information along with the audio information be issued. In the case of ASVOB, however, is the video information still picture information which contains only one picture.

The VOB and the reproduction method of AOB and ASVOB are in the following Points different from each other.

A first difference is the storage position of the data. In the case of VOB, the audio information and the Video information bundled together and recorded on the optical disk as a system data stream. In the case of AOB and ASVOB, the audio information and the Video information in different areas of the optical disc recorded as different system data streams.

A second difference is the synchronization process the audio information and the still image information. Become VOBs for sequential playback by a decoder processed. An STC, which represents a reference clock, is represented by an SCR (system reference clock) in the "Pack of the file header "in first pack of the system data stream reset. The decoder gets on the STC to get the audio information and the still picture information to clock the output represented by the PTS in the header of the "package" in each pack will spend.

AOBs and ASVOBs become simultaneous for playback processed by a decoder. A variety of ASVOBs, which are to be reproduced in synchronization with an AOB read from the optical disc and into the decoder in front of the AOB entered. The entry of the ASVOBs in the decoder is not immediate shown, in contrast to the VOB. The ASVOBs are in line decoded with the MPEG decoding model. Specified is the STC, which is a reference watch reset by the SCR in the first pack of each ASVOB. The ASVOB is in compliance decoded with the PTS in the packet. It can be assumed that the post-coding data of the plurality of ASVOBs which are reproduced should be accumulated in synchronization with the AOB, in the decoder, but actually are predecoded ASVOB data in an appropriate buffer in the Decoder accumulated.

When ASVOB completely entered into the decoder AOB is read from the optical disc and into the decoder entered. When AOB has been entered into the decoder, the STC as a reference watch by the SCR in the first pack of the AOB in a similar one Way reset compared to the case of VOB. The decoder gets relying on the STC to issue the AOB at an output clock, which is represented by the PTS in each header pack becomes.

The information that the output clocking represent the ASVOB, are in the display list contained in the PGC information stored. The area of the optical disc that contains the information which indicate the output timing of the ASVOB is different from the area of the optical disk that stores the ASVOB. The Information indicating the output clock of the ASVOB will sent to the decoder separately from the ASVOB. Every ASVOB in the Decoder is not output in synchronization with the STC, but will be in agreement with the information that the output clock of the ASVOB, which stored in the display list, specify, output.

The output clock is therefore the AOB predetermined by the PTS, which are associated with the AOB itself, the output clocking of the ASVOB by the information in the Display list which is different in an area from the area, that stores the ASVOB is predetermined.

The video decoder 87 decodes the video data in the video buffer 96 are saved. The sub video decoder 98 decodes the sub-video data contained in the sub-video buffer 105 are saved.

The audio decoder 100 decodes the audio data in the audio buffer 99 are saved. The output from the audio decoder 100 (the decoding result) is output as an audio output.

The video mixing section 101 mixes the output of the video decoder 87 (Decoding result) and the output from the sub video decoder 98 (Decoding result) to generate a group of video data. The output from the video mixing section 101 is output as a video output.

The section 102 the synchronization setting manages the synchronization of the work steps of the highlighting decoder 95 , the video decoder 87 , the sub video decoder 98 and the audio decoder 100 ,

Before the playback starts, the control panel section determines 93 whether the playback mode is video-oriented or not. If the playback mode is determined to be video-oriented, the video manager is read out based on the information read out from the data management area of the data carrier.

The control panel section 93 refers to the PGC management information table for the video manager menu to calculate a play address of the program chain for the disk menu. The control panel section 93 plays the playback address and keeps it inside. If the play address of the program chain for the disk menu has been kept inside, the control panel section refers 93 the PGC hold information, around the video object (VOB) to be reproduced and its reproduction address on the optical disk 100 , to calculate. When the video object to be played is determined, the control panel section 93 a control signal to the section 83 mechanism control and section 84 for signal processing to get the specific video object from the optical disc 100 and plays the video object in the following manner.

The VOB is in the AV decoder section 85 entered. A decoding stream instruction "VOB playback" becomes the AV decoder section 85 from the control panel section 93 given up.

The VOB data stream that goes into the AV decoder section 85 was entered into various packets contained in the VOB data stream by the decoder section 88 of the VOB system. Audio, video, sub-video, and highlight information packets are each in the audio buffer 99 , the video buffer 96 , the sub video buffer 105 and the highlight buffer 94 entered. The highlight buffer 94 buffers only the highlighting information in the PCI (highlighting) packet in the highlighting information packet.

The data entered in each buffer is in the audio decoder 100 , the video decoder 87 , the sub video decoder 98 and the highlight decoder 95 entered for decoding.

The audio information for the menu is provided by the audio decoder 100 output. The output from the video decoder 87 and the output from the sub video decoder 98 are through the section 101 mixed together for video mixing. The mixing result is output as a video output. The output of the highlight decoder 95 is in the Control Panel section 93 read. As a result, the button information or the like of each menu is stored in the memory of the system control section 93 saved.

In this way, a Menu displayed, which allows the user to choose from a variety of titles select.

24 shows an exemplary menu.

The user sees the video menu, which in 24 is displayed, and selects and closes one of a large number of contents in the video menu. For example, the user selects and completes content that he / she is interested in.

It is assumed that the user names a number of the menu content that corresponds to either one of Title 1, Title 2 or Title 3, which in 24 are shown, corresponding to the remote control 91 used. The control panel section 93 receives the name of the menu content number from the remote control 91 and refers to the button information of the highlight information in the PCI (highlight) pack included in the VOB of the video menu which is reproduced to execute a control command corresponding to the designated number. The control command is e.g. B. "Play title #n", where "n" represents the title number to be played.

For the execution of the command "Game title #n" the Control Panel section on a pointer table for title search, which Part of the audio manager is the audio title set (ATS) and the track number to be determined in the ATS.

When the audio title set is selected, the control panel section 93 a control signal to the section 83 to control the mechanism and to section 84 for signal processing to reproduce the management information of the audio title set of the selected audio title set, successively reads in the search pointers of the audio title set PGC information set, which are part of the management information of the audio title set, and determines the PGC information of the Program chain for starting playback of the title that is to be played.

When the PGC information is determined, the control panel gives 93 a control signal to the control section 83 of the mechanism and section 84 signal processing to reproduce the specific PGC information and keep the PGC information in the inner buffer for the PGC information.

When the PGC information is held to start playback of the title, the system control selection refers to the held PGC information to obtain the ASVU number of the first audio program information. The control panel section 93 refers to the general information regarding the audio still video unit (ASVU_GI), which corresponds to the ASVU number, and the ASVOB, which corresponds to the first audio program of the PGC information from the optical disc, and gives the general information regarding the audio still video unit in the AV decoder section 85 on. A decode stream instruction "ASVOB playback" becomes the AV decoder section 85 from the control panel section 93 given. The AV decoder section 85 divides the ASVOB into packs and packets by the ASVOB system decoder section 103 and stores the packs and packages in the corresponding stores.

The size of the video buffer 96 must be equal to or greater than the maximum value of the sum of the sizes of the ASVOBs in the ASVU. To guarantee that the optical disc 100 is playable in every player, it is required that all playback devices have a video buffer 96 of a certain capacity or larger. A certain capacity is the maximum value of the total data volume of the "ASVOBs which are contained in the ASVU. In this example the maximum value is 2 MB. An I-picture has 100 KB to 200 KB and thus 10 to 20 I-pictures can be combined with the Audio information can be played back.

If all ASVOBs contained in an ASVU are completely in the ASVOB system decoder section 103 are entered, the highlighting decoder does not 95 , nor the video decoder 87 , still the sub video decoder " 98 a decode tion. When all the ASVOBs are stored in the corresponding memories, the audio object to be reproduced and the reproduction address thereof are determined by the information table regarding the audio title set program and the reproduction information table relating to the audio title set cell. The AOB determined in this manner is represented by a control signal output to the section 83 the mechanism controller and the signal processing section 84 ,

The AOB, which from the optical disc 100 has been read is in the AV decoder section 85 entered. A decoding stream instruction "AOB playback" is inserted into the AV decoding section 85 from the control panel section 93 entered. The AOB is through the decoder section 104 of the AOB system transformed into an audio data stream. The audio data stream becomes the audio decoder 100 through the audio buffer 99 entered. The audio data is thus prepared for output. When the audio data is prepared for output, the STC (reference clock) is in the section 102 reset for synchronization setting by the SCR in the first pack of the AOB. The audio data of the AOB. with the timing of the PTS, which is stored in the file header of the packet. When the output of the AOB is started, the first I-picture of the ASVOB and the highlight information and the sub-picture information for the menu content to be displayed in an overlap status with the I-picture are decoded and at the instruction of the section 102 issued for synchronization setting. It is not guaranteed that the PTS is described in all of the AOB's packets, but the audio decoder 100 outputs the audio data as it complements the PTS.

The control panel section 93 holds the still picture reproduction information of the PGC information. The still picture reproduction information includes the display timing of the still pictures. The control panel section 93 gives the display control information of the still picture information to the section 102 for setting the synchronization of the AV decoder section 85 in accordance with the display timing of the reproduction information of the still picture. The reproduction control information contains a waiting period until the I-picture of the ASVOB to be renewed is determined, and the display thereof is displayed. The section 102 the video decoder points to the synchronization setting 87 to output the specific I-picture at the specific timing in accordance with the input display control information.

In other words, the ASVOB in accordance with the display timing information is stored in an area different from that The area that stores the ASVOB is, in contrast, saved on the case of AOB or VOB.

In this way, the ASVU data corresponding to the audio data are all stored in the corresponding memories before the audio data is reproduced. Therefore, the highlight buffer 94 , the video buffer 96 and the sub video buffer 105 have a capacity greater than that of the buffers defined in the MPEG2 or DVD video standard.

25 is a flowchart of an exemplary operation of the DVD player 1 when the menu button 194 the remote control 91 is pressed.

When the user presses the menu button 194 the remote control 91 presses, receives the remote control receiving section 92 a signal that the menu button 194 was pressed (step S2501 ).

The control panel section 93 determines whether or not an existence flag exists for the specified video data stream with the value "1" among the existence flags of the specified video data streams corresponding to the program (PG) which is currently being reproduced in the held PGC information ( ie whether the specified video data stream exists or not) (step S2502 ).

If it is determined that all existence flags of the specified video streams in step S2503 Are "0", the AMG menu playback process ( 27 ) called (step S2504 ).

If it is determined that an existence flag of a specified video data stream with the value "1" is among the existence flags of the specified video data streams in the step S2503 exists, the playback process of the specified video data stream ( 26 ) called (step S2505 ).

26 is a flowchart of the playback process of the specified video data streams. The playback process of the specified video data stream indicates the playback of a specified still image from a plurality of still images corresponding to the audio program. The specified still picture is e.g. B. used as a menu that allows the user to select one of the variety of still picture groups.

The control panel section 93 sends display control information indicating the display of the ASVOB for the specified video data stream from the held PGC information of the section 102 assigns for the synchronization setting (step S2601 ). The ASVOB for the specified video data stream is e.g. B. the last ASVOB in the ASVU.

The section 102 the video decoder points to the synchronization setting 87 to display the I-picture determined by the display control information (step S2602 ).

The video decoder outputs the I-picture that is used for the menu from the I-pictures that are in the video buffer 96 are held to the video mixing section 101 off (step S2603 ).

The section 102 the sub video decoder has to set the synchronization 98 to display the sub-video determined by the display control information (step S2604) ,

The sub video decoder 98 returns the sub-video used for the menu from the sub-videos stored in the sub-video buffer 105 are held to the video mixing section 101 off (step S2605 ).

The video mixing section 101 mixes the I-picture that is used for the menu and that from the video decoder 27 and the sub-video used for the menu and which from the sub-video decoder 98 has been output and outputs the mixing result (step S2607 ).

An image in which the I-picture for the menu and the sub-video for the menu have been superimposed is output to the video output (step S2608 ). The picture is on z. B. the TV monitor 2 which is connected to the DVD player is displayed. The user can view the image on the TV monitor 2 is displayed.

27 Fig. 4 is a flowchart of the process of rendering the AMG menu. The playback process of the AMG menu shows the playback of the AMG menu, which is a video menu that allows the user to select a title from a variety of titles included in 24 are shown, so that it can be played back.

The control panel section 93 reads out an audio manager based on the information read from the file management area of the volume (step S2701 ).

The control panel section 93 refers to the PGC management information table for the menu of the audio manager to calculate and reproduce the recording address of the program chain of the volume menu and to keep the recording address inside (step S2702 ).

When the recording address of the program chain of the volume menu is kept inside, the system control section refers 93 on the held PGC information, around the video object (VOB) to be reproduced and its recording address on the optical disk 100 to calculate (step S2703 ).

When the video object to be played is determined, the control panel gives 93 a control signal to the section 83 for mechanism control and signal processing section 84 to the predetermined video object (VOB) from the optical disc 100 to read and play the video object (step S2704 ).

The VOB system data stream is in the AV decoder section 85 entered. At the same time, a decoding stream instruction becomes "VOB playback" from the system control section 93 to the AV decoder section 85 given. (Step S2705 ).

The VOB data stream input to the AV decoder section 85 is through the VOB system decoder section 88 divided into different packs, ie audio, video, sub-video and highlight information packs contained in the VOB data stream. (Step S2706 )

The packs are each in the audio buffer 99 , the video buffer 96 , the sub video buffer 105 and the highlight buffer 94 entered (step S2707 ). The highlight buffer 94 buffers only the highlight information in the PCI (highlight) packet in the highlight information pack.

The data input in each buffer is used for decoding in the audio decoder 100 , the video decoder 87 , the sub video decoder 98 and the highlight decoder 95 entered (step S2708 ).

The audio information for the menu is provided by the audio decoder 100 output. The output from the video decoder 87 and the output of sub video decoder 98 are mixed together by the video mixing section 101 and spent (step S2709 ).

The output from the highlighting decoder 95 is in the Control Panel section 93 read. As a result, the button information or the like of each menu is stored in the system control section 93 saved. In this way, the AMG menu, which is in 24 is shown.

28 FIG. 14 shows an image of a title generated by the playback process of the specified video data stream which is described with reference to FIG 26 is described, can be generated.

In 28 put the reference numbers 2801 to 2810 Still pictures represent, which are reproduced together with audio information of high quality. The dotted arrows represent the order in which the still images are displayed.

28 shows a still picture group 2820 , which is labeled with "pictures", a still picture group 2830 , which is labeled with "biography", a still picture group 2840 , which is labeled with "credits". Here, the term "still picture group" refers to a plurality of one or more still pictures which are grouped together.

The still picture group 2820 e contains still pictures 2803 to 2806 which are photos of melody performers and photos that relate to the melody. The still picture group 2830 contains still images 2807 and 2808 which contain a summary of the career and a list of works by the interpreters of the melodies as well as texts and photos. The still picture group 2840 contains still images 2809 and 2810 which represent the interpreters, the recording engineers, the producers and the like of the melodies, mainly as texts.

The still picture 2802 , which is labeled with "Menu", is used to select one of a variety used by still picture groups. On the still picture 2802 become an "images" button 2851 and a "biography" button 2852 and a "credit" button 2853 displayed.

The still pictures 2801 to 2810 , what a 28 are reproduced in the order shown in the reproduction control information stored on the optical disk 100 is stored, is described. The still picture 2802 However, it is structured in such a way that it is displayed in response to an input from the user after switching from any other still picture. For example, the still picture which is being reproduced becomes a still picture without any interruption in the sound reproduction 2802 toggled when the user pressed the menu button 194 on the remote control 91 presses while the still picture group 2820 , which is labeled with "pictures" is reproduced. As a result, any of the still picture groups 2820 . 2830 and 2840 to be selected.

If the "Pictures" button 2851 while the still image is displayed 2802 is selected, the still picture 2802 into a still picture in the still picture group 2820 switched without any interruption in sound reproduction (e.g. the still picture 2803 ). If the "Biography" button 2852 or the "end credits" button 2853 is selected while the still picture 2802 is displayed, the still picture 2802 switched to another still image in a similar manner.

For displaying the still picture 2802 the above-mentioned ASVOB is used for the specified video data stream.

In 28 represents the reference number 2860 flag information indicating that a specified still picture as a menu from the plurality of still pictures 2801 to 2810 acts.

The flag information 2860 contains a variety of specified video stream existence flags 2871 to 2880 , each with a variety of still images 2801 to 2810 correspond. Any of the plurality of specified video stream existence flags 2871 to 2880 can in z. B. the display list 1071 as a specified video stream existence flag 1102 like him in the 11A to 11D is shown to be included.

In the example, which in 28 is shown is the still picture 2802 the specified still image, which acts as a menu.

Accordingly, the value of the existence flag is 2872 of the specified video data stream corresponding to the still picture 2802 set to the value "1". The value of the specified video stream existence flag 2871 and 2873 to 2880 will correspond to all other still images 2801 and 2803 to 2810 set to "0". If the menu button 194 on the remote control 91 is pressed, the still picture 2802 according to the existence flag 2872 of the specified video data stream is displayed with the value "1", regardless of which other still picture is currently being reproduced.

The value of "0" of all specified video stream existence flags 2871 to 2880 that in the flag information 2860 indicates the large number of still images 2801 to 2810 does not contain a specified still image that acts as a menu.

The flag information 2860 can be defined for any variety of audio programs included in the audio title set (e.g., a variety of melodies).

By using the flag information 2860 , which is defined for each variety of audio programs (e.g. a variety of melodies) and which is contained in the audio title set, can be used for various specified still images (e.g. menus) for different audio programs (e.g. different melodies) by a common button (e.g. the menu button 194 the remote control 91 ) be called.

The present invention is not limited to the examples described above.

In the example above, the existence flag 1102 the specified video data stream in the playback information of the audio still video (ATS_ASV_PBI) 1029 saved as in the 11A to 11B shown. The location of the existence flag 1102 however, the specified video data streams are not limited to this. The existence flag 1102 of the specified video data stream can be in other positions on the optical disk 100 get saved. Alternatively to the existence flag 1102 additional information of the specified video data stream can be added and stored. In this way, high-speed reproduction can be realized.

For example, the area in each of the 11A and 11B ("Slide show mode") which shows the program number 1104 stores, through a reserved area in each of the 11C and 11D ("Browse mode") replaced. In the case where the existence of the existence flag 1102 of the specified video data stream is only permitted in "browse mode", the number of the display list of the audio still video (ASV_DLIST) 1071 , which relates to the specified video data stream for the menu, are stored in the reserved area. Especially when the number is "0", it is clear that there is no specified video stream for the menu; and if the number is not "0", it is clear that the number is the number of the ASV_DLIST to which it should refer.

With reference to 10 can the bit 7 the playback mode of the audio still video (ASV_DMOD) 1062 in the search pointer of the audio still video playback information (ATS_PG_ASV_PGI_SRP) 1028 in the playback information table of the audio title set audio still video (ATS_ASV_PBIT) 1014 be a reserved area. In such a case, a flag indicating whether the specified video data current for the menu in this program (PG) exists or not, in bit 7 ASV playback mode 1062 be included. In this case, it is easier to confirm that there is no specified video stream for the menu in the program (FG) than in the case of the existence flag being included 1102 the specified video data stream in the display list 1071 the audio still videos (ASV_DLIST), which are in the 11A to 11D are displayed. The reason for this is that if the flag is in bit 7 ASV playback mode is recorded 1062 , it is possible to confirm that there is no specified video data stream for the menu in the PG program, mainly by checking the bit 7 ASV playback mode 1062 instead of checking all existence flags 1102 of the specified video streams in the display list 1071 ,

With reference to 10 can bit 7 and bit 6 the playback mode 1062 the audio still video (ASV_DMOD) in the search pointer of the playback information of the audio still video (ATS_PG_ASV_PGI_SRP) in the playback table of the audio title set audio still video (ATS_ASV_PBIT) 1014 reserved areas. In such a case, a specified video stream existence flag can be in each of the bits 7 and bits 6 be included when bit 7 ASV playback mode 1062 Is "1", it is clear that the ASVOB, which is in the first display list of the audio still video (ASV_DLIST) 1071 in the playback information of the audio still video (ATS_ASV_PBI) 1029 by the search pointer 1028 the audio still video playback information has been named, is the specified video stream used as a menu. If bit 6 ASV playback mode 1062 "1", it is clear that the ASVOB, which is in the last display list of the audio still video (ASV_DLIST) 1071 in the playback information of the audio still video (ATS_ASV_PBI) 1029 which is indicated by the search pointer 1028 the playback information of the audio still video has been named, which is the specified video data stream which is used as a menu. With this method, the playback device can always determine whether or not there is a specified video data stream used as a menu by referring back to the specified position.

With reference to 10 can use bits 7 to 4 of playback mode 1062 the audio still video (ASV_DMOD) in the search pointer of the playback information of the audio still video (ATS_PG_ASV_PGI_SRP) 1028 in the playback information table of the audio title set audio still video (ATS_ASV_PBIT) 1014 be a reserved area. In such a case, the number of the display list 1071 of the audio still video, which relates to the specified video data stream, in bits 7 to 4 ASV playback mode. Particularly when the number is "0", it is clear that there is no specified video stream for the menu; and if the number has a value other than "0" (1 to 15), it is clear that the number is the number of the ASV_DLIST to which it should refer. With this method, the playback device can determine whether there is a specified video data stream or not and the position of the specified video data stream by referring to the search pointer of the playback information of the audio still video 1028 specify. As a result, the search performed by the playback device becomes easier.

With reference to 10 can the fifth bit of the program information of the audio title set (ATS_PG) 1026 in the information table of the audio bibliographic record program (ATS_PG_IT) 1012 be a reserved area. In such a case, the number of the display list of the audio still video (ASV_DLIST) 1071 , which refers to the specified video data stream in the fifth byte of the program information of the audio title set (ATS_PG) 1026 be increased. Especially when the number is "0", it is clear that there is no specified video stream for the menu; and if the number has a value other than "0" (1 to 255), it is clear that the number is the number of the ASV_DLIST to which it should refer. With this method, the reproducing apparatus can determine whether or not there is a specified video data stream and the position of the specified video data stream by referring to the program information of the audio title set 1026 specify. As a result, the search performed by the playback device is easier.

With reference to 8th can the bits 55 to 50 the general information of the audio still video unit (ASVU_GI) in the management information of the audio still video unit (ASVUI) 811 be a reserved area. In such a case, the number of the display list 1071 of the audio still video (ASV_DLIST), which relates to the specified video data stream, is stored in bits 55 to 50 of the general information of the audio still video unit. Especially when the number is "0", it is clear that there is no specified video stream for the menu; and if the number has a value other than "0" (1 to 63), it is clear that the number is the number of the ASV_DLIST to which it should refer.

In the example described above, when the menu button 194 the remote control 91 is pressed, the AMG menu is displayed where the flag of the specified video stream is "0" and the ASVOB for the specified video stream for the menu is displayed when the specified video stream flag is "1". Alternatively, the AMG menu and ASVOB can be displayed for the specified video data stream for the menu can be assigned to different buttons. For example, it can be structured so that when the "title" button on the remote control 91 is pressed, the AMG menu is played back; and when the "Menu" button is pressed, the ASVOB for the specified video stream for the menu is played.

As described above, according to the optical Plate, of the playback device and the playback method of the present invention specified still images, e.g. B. Menus, for different audio programs (e.g. different melodies contained in an audio title are) called up by operating a common button.

The specified still picture can can be played without interruption in the sound.

Because different specified still images (e.g. menus) to various audio programs (e.g. different melodies) can be displayed, an optimal menu for each from the variety of audio programs can be displayed.
